The similarity in voices among blood relations has been always a fascinating subject in forensic phonetics. The present work is an initiatory study of investigational character that explains the resemblance of mother and her daughter phonation. This study is an attempt to report a novel approach to the speaker recognition and comparison of the voice of mother and her daughter by the use of voice biometric software. An attempt has been made to enlighten the role of voice as evidence in forensic investigation. Having noted a lack of oral corpora of mother and daughter voices, we have collected a database which consists of the 40 samples in a combination 20 each of mother & daughter respectively. Voice transcripts of mother and daughter were analyzed & compared using speech analysis software to examine the similarities & variations in sound spectrograms. The results of our study showed that the mother and daughter voice samples have higher similarities which were estimated to 88%-92%. It is due to the influence of genetic endowment, physical similarities and inheritance of vocal gesture & posture. Voice Biometrical Match cannot be 100% due to law of individuality. This suggests that the system features are to a great extent genetically conditioned and that they are hence useful and robust for comparing speech samples of known and unknown origin, as found in legal cases. This research shall enlighten an idea of getting corroborative evidence, further which can be a part of Forensic Investigation. Forensic experts can contribute to society/law with advance as well as fast crime detection solutions challenge in speaker identification.
